Buy a new toilet


The first decision that has to take when thinking of buying a new toilet is its shape. You can choose from round or elongated models. The round toilets occupy less space and are ideal for small bathrooms. Then we also have to consider the height of the toilet. As you probably will not replace it again, keep in mind your future needs.

There are the typical models on the market that come in two parts (toilet and water tank) and the model with only one part. The latter are more modern and have a more attractive design. They are also easier to install. Of course, being only in one part, are heavier and more difficult to put into place.

Compared to tank, the new models take less water but their exhaust systems are so powerful that the only difference you'll notice is the water savings.

Finally, you should take into account the color of the model to buy. The color models are more expensive than the typical white.

When purchasing your new toilet, do not forget to also purchase the new bolts and a new base on which to install the toilet.

Begin Toilet Installation

Now that you have all the necessary parts, it's always good to start by cleaning the bathroom as well, especially around the toilet before removing it.

Then spread some old towels around in case the work becomes a little dirty.

Then remove the new toilet box and use the box to store trash. You will eventually put the old toilet in the box along with all the old parts.

Remove the old toilet


Turn off the water in the bathroom using the stopcock. If you have no security in the bathroom faucet, turn off the general water throughout the house. Then make a discharge to rid the reservoir of stored water. Open the water tank and wearing gloves and a sponge, remove any remaining water you find.

Place a small bucket under the barrel of water that is connected to the tank and unscrew the threaded barrel on the side of the reservoir using the hands or, if necessary, a spanner. If you're going to replace the barrel of water, repeat the process on the opposite side and remove the tube altogether. You can now remove the valve that controls reservoir filling and pour it into the trash. Everything else can stay in the tank.

Then you remove the tank altogether. Look for screws that secure the tank to the wall and using a spanner, loosen them. The tank should exit without difficulty.

Now you need to remove the toilet. To do this, loosen the screws that hold the toilet to the base and then shake it a bit to loosen it. With the help of another person, lift the toilet and place it inside the box of new toilet. Unscrew the old base of the toilet and throw it away. Place an old rag in the drain pipe. The rag will prevent sewer gases stink up your entire bathroom. Now scrape off any residue that may have formed on the floor where the toilet was placed.

Install New Toilet

First you must install the new base. Put it in place and tighten the screws until the end so that they do not prevent the new toilet to seat in correctly.

Place the new toilet on its side and make sure all the rubber seals are in the correct place. Some models come apart and these closures are necessary to put them before installing the toilet. Now you can remove the rag from the drainpipe, and with the help of another person, put the new toilet into place. Make sure that the holes for the screws are aligned with the holes in the base. Before fixing the toilet in place, use a level to confirm that the toilet is right. If necessary, use plastic sheets to flush the toilet. Now you can tighten the screws and fix the toilet in place.

Your new toilet is almost installed. Just need to finish installing the new water tank. Remove all protective plastic that may stick to the shell. Put the new tank in place and make sure that all the pipes for the toilet are in the correct place. Now you can tighten the screws that hold the tank to the wall of your bathroom. The tanks come with valves fitted to all internal so no need to worry about this detail.

If you decided to change the water line pipe, wrap the tip of the barrel with a bit of Teflon tape and attach the pipe to the water inlet. Make sure the size of the barrel is enough to reach the reservoir and if necessary cut a little. Before tightening the nut on the inlet side of water, attach the pipe to the reservoir and tighten that side. Only then should tighten the nut on the side of the main water inlet.

When everything is finished, return the bucket below the entrance of water into the tank and open the stopcock. Make sure there are no leaks anywhere. Now you're ready to test your new toilet. Make some discharges and examine whether there is water pouring into some place.

Installing a new countertop in your toilet

Place the lid on your toilet again so that the holes in the lid align with the holes of the toilet. Insert the screws from top to bottom and place the screw at the bottom of the toilet. Go squeezing all the threads of all screws until the top is secure. If the cap is twisted, simply unscrew one of the threads and tighten the other.
Apply a sealant at the base of the toilet

It's always good to wait two or three days before applying the sealant. The toilet needs to settle before being sealed to the bathroom floor.

Place a thin layer of sealant around the base, leaving the scene of the bolts clean. Thus, any water that may leak from the toilet will be dissipated by the bathroom floor instead of being the cause of leaks.
